(N model.)

f0 all whom, it may concern.-

Be it known that L THOMAS THATOHER, a citizen of the United States, and a resident of the city of Utica, in the county of Oneida, State of New York, have invented a new and useful Improvement in an Axle End-Bearing; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters and figures marked thereon.

My invention relates to an improvement in the end-bearing of car or locomotive truck axles; and it consists in the mechanism hereinafter described.

In the accompanying drawings, Figure 1 represents a longitudinal section of the axle, collar, end-bearing, journal-bearing, cap, and oil-box, taken at line 00 :0, Fig.2. Fig. 2 represents an end view of theend-bearing with the end of the oil-box cut away, taken at line y Fig. 1. Fig. 3 represents a side view of my improved end-bearing. Fig. 4 represents a front external View of my improved endbearing. Fig. 5 represents a plan view of one ofthe revolving disks. Fig. 6 represents a vertical section of the same, taken at z 2, Fig. 5. Fig. 7 represents a plan view of the other revolving disk. Fig. 8 represents a vertical section of the same, taken at line to 20, Fig. 7. Fig. 9 represents a plan View of the seat for the revolving disks. Fig. 10 represents a vertical section of the same, taken at line 8 s, Fig. 9.

Having described my invention by reference to the figures in the accompanying drawings, I will now proceed to describe it by reference to theletters marked thereon, in which similar letters refer to corresponding parts throughout the several views.

or represents the axle of a car.

a represents an ordinary collar turned on the end of the axle.

(t represents the ordinary brass journalbearing fitted to the axle.

a represents the oil-box which surrounds and incloses the journal and axle.

a represents a projecting lug'on the top of the oil-box, to which a lid is usually attached to inclose the box.

posite the end of the axle and against the walls of the oil-box, and adapted to rotate by friction when brought in contact with the end of the axle.

b represents the seat in which the revolving disks are supported.

12 represents a bolt-h ole passing through the upper surface of the seat to receive a retaining-bolt.

b represents a depression in the seat for the reception of the revolving disks, to retain them in position and receive any side strain.

11'' represents strengthening braces on the external surface of the seat.

0 represents a projecting lug on the inside of the 0il-box, against which the lower portion of the seat rests when in position.

0 represents a retaining-bolt, which passes through bolt-holes in thesides of the oil-box, through aperture 1) in the seat, bolting and clamping the seat rigidly in position to receive the end-thrusts, as described.

It is obvious that other means than those described for securing the seat to the oil-box may be used without interfering with the usefulness of my invention.

(3 represents a revolving disk,with a depression or offset in the center of the same adapted to fit into the corresponding depression, b in the seat, and is provided with a circular aperture in the center.

cl represents the depression or oftset in disk (1.

d representsacircularaperturein the same.

0 represents a revolving disk with one surface adapted to fit the end of the axle, provided with a projecting surface upon the opposite side adapted to fit in depression at in usefulness of my invention.

the other revolving disk, provided with a central shank adapted to fit into the central holes of the other revolving disk and seat, and provided with a nut or rivet for holding the revolving disks and seat together.

s represents the projecting surface on the revolving disk 6.

6 represents the projecting shank on the same.

e represents a nut on the end of the shank.

It is obvious that the number and shape of the revolving disks may be increased, diminished, or changed without interfering with the These disks,however, must be held in the oil-box opposite the end of the axle and against the walls of the oil-box, so that the oil-box will receive the thrusts, and so constructed as to rotate when the end-thrusts'of the axle are brought in contact with the disk. I prefer, however, two revolving circular disks with depressions and ofl'sets, as described.

1 The drawings illustrate an axle with a col- My improved end-bearing may be used on axles with or without collars.

A concurrent application is herewith made by me for a patent for an improvement in an axle end-bearing ofacar and locomotive truck, for a disk supported and held in an oil-box against the end of an axle for taking the endthrusts of the same. I do not claim a stationary disk in this application.

What I claim as new, and desire to secure by Letters Patent, is

1. The herein described axle end-bearing having a stationary and removable seat with a deprcssiontherein, provided on the upper surface with an aperture for bolting the same rigidly to the oil-box, the lower surface resting against stationary supports in the oil-box, and one or more revolving disks to fit into the depression in the seat, combined and arranged substantially as stated.

2. The herein-described axle end-bearing having a stationary and removable seat with a depression therein, provided on the upper surface with an aperture for bolting the same rigidly to the oil-box, the lower surface resting against stationary supports in the oil-box, and one or more revolving disks to fit into the depression in the seat, with ashank thereon to fit into an aperture in the seat, as described.

3. The herein-described axle end-bearing having a stationary and removable seat with a depression therein, provided on the uppersurface with an aperture for bolting the same rigidly to the oil-box, the lower surface resting against stationary supports in the'oil-box, a revolving disk with offset and depression, with an aperture in the center for fitting into the depression in the seat,and a revolving disk with a projecting surface to fit the depression in the circular disk, and provided with acentral shank to fit the aperture in said circular disk and seat, and to secure the same together by nut or rivet, combined and arranged as described.
